Ironically the fact Oracle will be more expensive and have a bigger project footprint probably adds to its attraction at management level. It seems more "serious".
The VFP setup always seemed (when I was there) underresourced.
Also as others have mentioned the flexibility offered by the developers has caused the timescale to stretch.
The rigidity which may come with Oracle will help timescales but doubt if your users are going to be happy.
